Abstract: Sparse arrays, such as nested arrays and coprime arrays, can achieve a high number of degrees of freedom (DOFs) for direction of arrival (DOA) estimation with a reduced number of antennas.

Abstract: Compared to conventional uniformly spaced arrays, sparse arrays are effective and economical for many application scenarios. For example, sparse arrays can lower the peak sidelobe level ...

Prompts the user for a positive integer input (<100) and validates it. The function will continue to prompt the user until a valid input is received.
